No errors were detected.Includes only contours within the Raton Basin, Las Animas County, Colorado. Contours not well supported by data were deleted.A raster was created from the contours of the altitude of the top of the Trinidad Sandstone, sir-06-5129_alt_top_trinidad_con, using the ESRI ArcGIS ArcInfo Workstation command, Topogridtool.20060313The raster data for the altitude of top of the Trinidad Sandstone was subtracted from raster data for land-surface altitude, using the ESRI ArcGIS Spatial Analyst extesnion, Math command, Minus, to create raster data for depth to the top of the Trinidad Sandstone.20060313Contours were generated from the raster data, using the ESRI ArcGIS ArcMap, Spatial Analyst Tools, Surface function, Contour.20060313Contours were clipped to the study area to coincide with the distribution of data points that were used to create the raster of the altitude of the top of the Trinidad Sandstone.20060313The contour lines were exported to a coverage, using the ESRI ArcGIS ArcMap Conversion Tools Feature Class To Coverage command.20060313The coverage was edited using the ESRI ArcGIS ArcInfo Workstation ArcEdit module. Editing consisted of deleting small closed contours and contours not supported by nearby data points, and manually re-shaping contours.20060313The edited coverage was exported to a shapefile and the contours were smoothed, using the ESRI ArcGIS Data Management Tools, Smooth function.20060313VectorString54Albers Conical Equal Area37.50000040.500000-105.50000037.0000000.0000000.000000coordinate pair0.0001280.000128metersNorth American Datum of 1983Geodetic Reference System 806378137.000000298.257222sir-06-5129_depth_top_trinidad_conContours showing generalized depth from land surface to top of Trinidad SandstoneU.S. Geological Survey Scientific Investigations Report 2006-5129FIDInternal feature number.ESRISequential unique whole numbers that are automatically generated.CONTOURLine of equal depth, evenly divisible by 500USGS5003500feetShapeFeature geometry.ESRICoordinates defining the features.indexContour type (index or intermediate)USGS0Intermediate contourUSGS1Index contour, every fifth contour, evenly divisible by 2,500USGSU.S. Geological SurveyAsk USGS -- Water Webserver Teammailing address445 National CenterRestonVA20192USA1-888-275-8747 (1-888-ASK-USGS)http://answers.usgs.gov/cgi-bin/gsanswers?pemail=h2oteam&amp;subject=GIS+Dataset+sir-06-5129_depth_top_trinidad_conDownloadable DataAlthough this data set has been used by the U.S. Geological Survey, U.S. Department of the Interior, no warranty expressed or implied is made by the U.S. Geological Survey as to the accuracy of the data and related materials.
